I've just try the blight to use blight wolf and be a melee fighter
But I could find any enhancements can give me 25% hp. (Without universal enhancement tree)
Does I miss anything?

I thought SSG just promise any melee fighter will have it's 20~25% hp in they're enhancements.

Druid's 25% in Nature's Protector enhancements, but now blight caster lost it.
